摘要： An optical wavelength grating coupler (102) incorporating one or more distributed Bragg reflectors (DBR) (434) or other reflective elements to enhance the coupling efficiency thereof. The grating coupler (102) has a grating (408) comprising scattering elements (103), and the one or more DBRs (434) are positioned with respect to the grating such that light passing through the grating towards the substrate (414) of the grating coupler (102) is reflected back by DBRs toward the grating. The DBR (434) comprises a multilayer stack of various materials and may be formed on the substrate (414). The grating coupler (102) may include a gas-filled cavity (472), where the cavity is formed by a conventional etching process and is used to reflect light toward the grating (408). The grating coupler (102) may also incorporate an anti-reflection coating (486) to reduce reflective loss on the surface of the grating.

摘要： High speed optical modulators (700) can be made of k modulators (740) connected in series disposed on one of a variety of semiconductor substrates. An electrical signal propagating in a microwave transmission line (710) is tapped off of the transmission line at regular intervals and is amplified by k distributed amplifiers (720). Each of the outputs of the k distributed amplifiers is connected to a respective one of the k modulators. Distributed amplifier modulators can have much higher modulating speeds than a comparable lumped element modulator, due to the lower capacitance of each of the k modulators. Distributed amplifier modulators can have much higher modulating speeds than a comparable traveling wave modulator, due to the impedance matching provided by the distributed amplifiers.

摘要： A polarization splitting grating coupler (PSGC) (100) connects an optical signal from an optical element (105), such as a fiber, to an optoelectronic integrated circuit (101). The PSGC (100) separates a received optical signal into two orthogonal polarizations and directs the two polarizations to separate waveguides on an integrated circuit (101). Each of the two separated polarizations can then be processed, as needed for a particular application, by the integrated circuit (1 O 1). A PSGC (100) can also operate in the reverse direction, and couple two optical signals from an integrated circuit to two respective orthogonal polarizations of one optical output signal sent off chip to an optical fiber.

摘要： High speed optical modulators (100) can be made of a reverse biased lateral PN diode (105) formed in a silicon rib optical waveguide (112) disposed on a SOI or other silicon based substrate (100). A PN junction is formed at the boundary of the P and N doped regions (120, 130) The depletion region at the PN junction (106) overlaps with the center of a guided optical mode propagating through the waveguide (110). Electrically modulating a reverse biased lateral PN diode (105) causes a phase shift in an optical wave propagating through the waveguide (110). Prior art forward biased PN and PIN diode modulators have been relatively low speed devices.
